-Characteristics of SAMSUNG INR18650-15M-
This “Standard charge” means charging the cell with charge current 750mA and constant voltage 4.2V 100mA cut-off at 25℃.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 1500mA with 2.5V cut-off at 25℃ within 1hour after the standard charge.
Standard discharge capacity ≥ 1,450mAh
Standard rated discharge capacity
The standard rated discharge is the discharge capacity of the cell, which is measured with discharge current of 10A with 2.5V cut-off at 25℃ within 1hour after the standard charge.
Standard rated discharge capacity ≥ 1,450mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge. Initial internal impedance ≤ 25mΩ
Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the standard charge is
If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours. Percentage as an index of the Standard discharge capacity (=1450mAh) is 100%
Temperature Dependence of Charge Capacity
